A. 
General. The Borough is hereby divided into districts of different types, each type of such number, shape, kind and area, as well as of such common unity and purpose and adaptability of use that is deemed most suitable to carry out the objectives of this chapter and the Comprehensive Plan. These districts are designated and abbreviated in § 455-35 of this chapter.
B. 
Zoning Map. Zoning districts are bounded and defined as shown on the map entitled "Zoning Map of the Borough of West Reading," as in effect from time to time, which accompanies this chapter and which, with all explanatory matters herein, is hereby made a part of this chapter.
C. 
Interpretation of district boundaries. Where uncertainty exists with respect to the boundaries of the zoning districts, as indicated on the Zoning Map, the following rules shall apply:
(1) 
Where district boundaries are indicated as approximately coinciding with the center lines of streets, highways, railroad lines, or streams, such center lines shall be construed to be such boundaries.
(2) 
Where district boundaries are so indicated that they approximately coincide with lot lines, such lot lines shall be construed to be the district boundaries; or where district boundaries are extensions of lot lines or connect the intersections of lot lines, such lines shall be the district boundaries.
(3) 
Where district boundaries are so indicated that they are approximately parallel to center lines of streets or highways, such district boundaries shall be construed as being parallel thereto, and at such distance therefrom as indicated on the Zoning Map.
(4) 
Where district boundaries divide a lot, any use authorized or permitted in either zone may be extended a distance not to exceed 50 feet beyond the boundary of the zone in which such use is permitted or authorized.
